Achilles tendonitis is one of the most common running injuries. The achilles tendon is the large tendon at the back of the ankle. It connects the calf muscles made up of the gastrocnemius and soleus to the heel bone or calcaneus. It provides the power in the push off phase of walking and running where huge forces are transmitted through the achilles tendon. Achilles tendonitis is often now referred to as achilles tendinopathy. This is because the term tendinopathy covers all types of overuse achilles tendon injury. Strictly speaking tendonitis suggests an inflammatory condition of the tendon but in reality few achilles tendon injuries are actually down to pure inflammation. Soleus muscleThe main finding, particularly in older athletes is usually degeneration of the tissue with a loss of normal fibre structure. Other very similar conditions may actually be due to inflammation or degeneration of the tendon sheath which surrounds the tendon rather than the achilles tendon itself. In addition to being either chronic or acute, achilles tendonitis can also be at the attachment point to the heel called insertional achilles tendonitis or in the mid-portion of the tendon typically around 4cm above the heel. Healing of the achilles tendon is often slow, due to its poor blood supply.
Achilles tendonitis most commonly occurs due to repetitive or prolonged activities placing strain on the Achilles tendon. This typically occurs due to excessive walking, running or jumping activities. Occasionally, it may occur suddenly due to a high force going through the Achilles tendon beyond what it can withstand. This may be due to a sudden acceleration or forceful jump. The condition may also occur following a calf or Achilles tear, following a poorly rehabilitated sprained ankle or in patients with poor foot biomechanics or inappropriate footwear. In athletes, this condition is commonly seen in running sports such as marathon, triathlon, football and athletics.
The main symptom of Achilles tendonitis is a feeling of pain and swelling in your heel as you walk or run. Other symptoms include tight calf muscles and limited range of motion when flexing the foot. This condition can also make the skin in your heel feel overly warm to the touch.
The diagnosis is made via discussion with your doctor and physical examination. Typically, imaging studies are not needed to make the diagnosis. However, in some cases, an ultrasound is useful in looking for evidence of degenerative changes in the tendon and to rule out tendon rupture. An MRI can be used for similar purposes, as well. Your physician will determine whether or not further studies are necessary.
Ask your Pharmacist for advice. 1) Your Pharmacy stocks a range of cold packs which may be applied to the area to decrease inflammation. 2) Ask your Pharmacist about a temporary heel raise or pad which can be inserted into footwear to decrease the force absorbed by the tendon when the feet land heavily on the ground. 3) Gently massaging a heat-producing liniment into the calf can help to relieve tension in the muscle which may relieve the symptoms of Achilles Tendinitis. Ask your Pharmacist to recommend the most appropriate type. 4) Gels, sprays or creams which help to reduce inflammation are available and may be applied to the injured area. Ask your Pharmacist for advice. 5) Your Pharmacist can advise you on analgesic, anti-inflammatory medications such as Aspirin which may be of assistance. Aspirin should be avoided in children under the age of 12 and those aged 12 to 15 who have a fever. 6) Strapping the ankle can help restrict movement and minimise further injury. Your Pharmacist stocks a range of athletic strapping tape and ankle guards which may assist your injury.
For paratenonitis, a technique called brisement is an option. Local anesthetic is injected into the space between the tendon and its surrounding sheath to break up scar tissue. This can be beneficial in earlier stages of the problem 30 to 50 percent of the time, but may need to be repeated two to three times. Surgery consists of cutting out the surrounding thickened and scarred sheath. The tendon itself is also explored and any split tears within the tendon are repaired. Motion is started almost immediately to prevent repeat scarring of the tendon to the sheath and overlying soft tissue, and weight-bearing should follow as soon as pain and swelling permit, usually less than one to two weeks. Return to competitive activity takes three to six months. Since tendinosis involves changes in the substance of the tendon, brisement is of no benefit. Surgery consists of cutting out scar tissue and calcification deposits within the tendon. Abnormal tissue is excised until tissue with normal appearance appears. The tendon is then repaired with suture. In older patients or when more than 50 percent of the tendon is removed, one of the other tendons at the back of the ankle is transferred to the heel bone to assist the Achilles tendon with strength as well as provide better blood supply to this area.
Stay in good shape year-round and try to keep your muscles as strong as they can be. Strong, flexible muscles work more efficiently and put less stress on your tendon. Increase the intensity and length of your exercise sessions gradually. This is especially important if you've been inactive for a while or you're new to a sport. Always warm up before you go for a run or play a sport. If your muscles are tight, your Achilles tendons have to work harder to compensate. Stretch it out. Stretch your legs, especially your calves, hamstrings, quadriceps, and thigh muscles - these muscles help stabilize your knee while running. Get shoes that fit properly and are designed for your sport. If you're a jogger, go to a running specialty store and have a trained professional help you select shoes that match your foot type and offer plenty of support. Replace your shoes before they become worn out. Try to run on softer surfaces like grass, dirt trails, or synthetic tracks. Hard surfaces like concrete or asphalt can put extra pressure on the joints. Also avoid running up or down hills as much as possible. Vary your exercise routine. Work different muscle groups to keep yourself in good overall shape and keep individual muscles from getting overused. If you notice any symptoms of Achilles tendonitis, stop running or doing activities that put stress on your feet. Wait until all the pain is gone or you have been cleared to start participating again by a doctor.
